Charles Hendrix, Michael Dunn's former next-door neighbor, describes violent behavior, lies, insurance fraud, cocaine use, bragging about putting a hit out on someone, and a first wife who said he'd held a gun to her head and threatened to kill her. He says Dunn bragged that he was smarter than everyone else and could outthink them.
Maybe the most chilling thing I've ever heard. (H/t Kevin Hayden.)
